So AAC 5.1, which I'm adding 2 further options.

1.) Passthrough of AC3 enable, Speaker Numbers 2.0 (expected AVR displays AC3)

All is fine.

2.) Passthrough of AC3 disabled, Speaker Number 2.0 set (expected AVR displays PCM and all channels should be transmitted as PCM 5.1)

All is fine.

2.) makes no sense. The relevant setting is AC3 Transcoding btw. and with 2.0 speakers set - _NO_ LPCM output, just 2.0. See 3.) which is funny.

3. 1.) Passthrough of AC3 enable, Speaker Numbers 5.1 (AVR displays PCM)

Only limited sound as originally experienced.

4. Passthrough of AC3 disabled, Speaker Number 5.1 set (expected AVR displays PCM)

Only limited sound as originally experienced.

Btw. AAC has nothing to do with AC3. In Kodi we just have a special mode to transcode LPCM to AC3, if user only has a SPDIF device or alternative only a 2.0 capable HDMI output, but an output capable of doing AC3. Therefore we decode to PCM and encode to AC3 and output.


So the best solution (at least for me with these scenarios) is as per your original suggestion, which was AC3 enable, speaker numbers 2.0, where everything outputs in a manner that works well.

In fact my soundbar also cannot do 5.1 - it just outputs 2.0 and the .1 is done automatically. In fact I really would wonder if it could do 5.1.
